- Description from novelbuddy

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

In her last life, Qu Zhi tried her best to be a good wife who was sensible and did not cause trouble, a filial and good daughter who helped her family, and a good mother who accompanied her children. However, Qu Zhi worked hard and suffered all her life. When she was about to die, she realized that in the end, all she got back for her hard work were complaints. Her husband complained that she was an idle, rich wife all day long who wasn’t satisfied with her happiness at home, and that she was a greedy woman.

But after decades of marriage, her husband had a firm, deadly hold on all her money, and she didn’t even have a dime to her name, nor a property to call her own. Every time she asked for money, he would trample all over her self-esteem. Her husband’s cold and sarcastic words made her unable to lift her head, and his friends would demean her while drinking wine, making her tremble with anger. This man had once said he would take care of her, yet he turned a blind eye! Those people focused on her happiness as a topic, and made a joke out of it.

Even her three children resented her for her uneven love towards everyone, and their relationship only became more strained as time passed. She had spent her whole life as a loner, and she had nothing. Lying on the operation table, Qu Zhi thought that if she could do it all over again, she wouldn’t be a housewife. She wouldn’t have given her second daughter away, and she wouldn’t take care of her blood-sucking relatives.

She wouldn’t marry her indifferent, cold husband either! When she next opened her eyes, she was back to twenty years in the past. Her eldest daughter was still in elementary school, and her second daughter had been in her belly for several months…

…but it seems pretty doable.
